I am away from my car for a few days and I want to order an electric water pump. Does anyone know the size of the hose that goes into the water pump so I can order the right size hose adapter fitting as well. engine is a 95 lt1 Thanks

 

EWP does not come as a whole unit, you need to dissasemble your old unit, put the electric motor in, and then seal it up. I personally like the CSR pump. In this case your old housing will be used, eliminating the need for any extra parts/adapters. Just don't forget to buy a relay kit for it as well.

thanks. I am going over to a double roller timing chain. The factory unit will clear all right then?

 

I don't think the timing cover will clear it

 

yes i didnt think so either. . .

 

i am looking at a picture of the factory unit. it looks like it should clear. . . we will see in a few weeks i guess

 

I think double rollers clear the timing cover with grinding. If not wouldn't the opti/WP have to move outward in that case? Then you would certainly need spacers for the WP.

 

The pin for the opti was what I was also wondering about as well.
